Hi,
I have a requirement where client uploads spread sheet containing thousands of
rows.
different columns of a row have different data type and the data must comply
with some validation rules.e.g.
below is a sample file structure:
Column_name Variable_type field_size i/p mask required_field
validation_Text
P/N String 20 yes
qty Integer 10 yes
Ship_From String 20 yes
Date Date MM/DD/YY yes
Status String 10 yes Failed
OR Qualified
while reading the xl sheet,I need to validate the data against the above
constraints and in case of any error in the data,
I need to store the error and inform the customer.
Please let me know the best possible approach maintaining the performance of
the system.
Any early responses will be much appreciated.
Thanks,
Ashish Gupta
